FAQs
Yes. SMS4RD3 is a 4-position receptacle designed for crimp contact termination and features a Push-Pull coupling for quick, reliable engagement. It is a free-hanging receptacle suitable for panel-mounted assemblies, reducing assembly time and field rework while maintaining robust electrical contact integrity in vibration-prone environments.
SMS4RD3 provides four contacts in a four-position layout with IP40 protection. It operates from -40 °C to 105 °C and carries a UL94 V0 flame rating, plus RoHS and REACH compliance. This combination supports reliable performance in harsh industrial environments and simplifies cross-border procurement.
The SMS4RD3 excels in compact control wiring for machine builders, process automation, and panel wiring where space is limited. Its four-position receptacle, crimp contacts, and Push-Pull coupling suit sensor/actuator networks and quick-connect wiring in tight panels, enabling faster diagnostics and easier field upgrades.
No. The connector specification notes no backshell possibility, which simplifies inventory and reduces accessory costs. This makes SMS4RD3 a lean choice for streamlined installations where space and cost efficiency are priorities, though you should plan for compatible mating components within the SMS series.
SMS4RD3 delivers faster mate/demate cycles with Push-Pull coupling and reliable crimp terminations, reducing assembly time and field service visits. Its compact, lightweight design conserves panel space and lowers weight-related costs, while RoHS/REACH and UL94 V0 compliance help minimize compliance-related risk and warranty expenses in manufacturing environments.
